Howth Coast Guard has successfully deployed its new remote operated vehicle (ROV) for the first time in a missing person exercise last night (Wednesday 30 October).

After several weeks of training, the coastguard team set out to locate a potential area of interest on the shore, and the rescue ROV was launched to conduct a sub-surface search.

An adult weighted target was then successfully located using the ROV camera and it was brought to the surface by the ROV using its gripping arm.

#SeaPower - The University of Limerick (UL) has unveiled a unique €2 million underwater robot adapted to inspect, repair and maintain marine renewable energy (MRE) facilities.

Funded by Science Foundation Ireland (SFI) through its Research Infrastructure Programme, the ROV Étaín can operate in challenging wind, wave, and tidal conditions.

Speaking at the launch of the robot at Limerick city docks yesterday (Thursday 26 April), Minister of State Pat Breen said: “Internationally, the offshore renewable energy sector is set to rapidly grow which will help to reduce carbon emissions and arrest climate change. 

“Ireland has the best wind and wave resources in Europe and it is vital that as an island nation we invest and engage in research in the area of marine energy technology. Therefore, I'm delighted to today launch this ROV which will support Ireland's growing offshore renewable energy sector.”

Researchers at UL’s Centre for Robotics and Intelligence Systems (CRIS) have enhanced a commercially available ROV system (Forum Energy Technology’s Comanche ROV) with UL-developed advanced control software (OceanRings), precision navigation and flight control, state-of-the-art robotic imaging and sonar systems and fully automated manipulator systems.

These advanced features allow the robot to operate in the challenging environment of ocean renewable energy to support inspection, repair and maintenance operations.

Prof Daniel Toal, director of the Centre for Robotics and Intelligence Systems at UL, explained why the ROV Étaín was developed. 

“Operation support in the MRE sector usually occurs on floating infrastructures so conditions are regularly beyond the capability and operating limits of commercial ROV technology. This means new smart ROV systems capability is necessary and that is what our team at UL has developed and launched today.”

UL’s Centre for Robotics and Intelligence Systems is part of the University College Cork-led SFI national Centre for Marine and Renewable Energy Ireland (MaREI).

The MaREI robotics lab at UL leads operations support engineering projects with industry partners such as Shannon Foynes Port Company, ESB, Ireland’s National Space Centre, SonarSim, Teledyne, Resolve Marine, CIL, IDS Monitoring and among others.

“The advanced robotics technology developed at UL will be crucial in supporting the burgeoning marine renewable energy sector,” said UL president Dr Des Fitzgerald. “It will also play a significant role in reducing the cost of installing and maintaining large-scale offshore energy generation infrastructure. 

“As the worldwide marine renewable energy sector grows, UL's research contribution in this area will have even greater impact. I am particularly happy to see this advanced UL technology being developed, trialled and launched in Limerick city docks. 

“The UL robotics base at the docks is just one of our commitments to grow and maintain strong links between the campus and the heart of Limerick city, with strategic partners like Shannon Foynes Port Company.”

Speaking about the project, Dr Ciarán Seoighe, deputy director general of Science Foundation Ireland, said the new ROV “will enhance our understanding of subsea exploration and marine renewable energy, placing Ireland at the forefront of advances in environmental research that are crucial to our country's future.”

#MarineNotice - Sailors and other mariners off the South West Coast should keep on the lookout for a visual survey by remote operated vehicle currently being undertaken by PSE Kindle Energy Ltd.

The survey, which was set to commence on Tuesday 9 May, will run for the next three weeks in the environs of the Kinsale Head Gas Field, subject to weather conditions, and is being carried out from the Skandi Olympia (Callsign C6XY8).

The vessel will have an ROV deployed close to the seabed and its travel rate (survey rate) is approximately 0.4 knots over the ground on a weather-dependent heading.

Regular safety messages will be broadcast on VHF Channel 16. All vessels, and particularly those engaged in fishing, are requested to give the Skandi Olympia a wide berth and keep a sharp lookout in the revenant areas, as detailed in Marine Notice No 19 of 2017, a PDF of which is available to read or download HERE.

In case of any doubt, call the vessel on VHF and a safe course to follow will be given.

The Marine Institute has issued a statement congratulating Mr Simon Coveney TD on his new appointment as the Minister for Agriculture, Marine and Food today (11th March 2011), during his visit on board the RV Celtic Explorer in Cork, after its return from the mission to the Labrador and Newfoundland Seas.

Seeing the capabilities of Ireland's largest research vessel and the work of the Marine Institute, Mr Simon Coveney highlighted the importance the Marine Sector has on the Irish economy. "The seas and ocean that surround the land of Ireland is arguably one of our countries greatest natural resources. Through marine research, development and sustainable management, Ireland is developing a strong reputation as an emerging centre of excellence, where we have prominent roles in many European and international marine science bodies," he said.

Ireland's national research vessels RV Celtic Explorer and RV Celtic Voyager will record 627 days at sea between the two during 2011. Their work will range from fisheries surveys to underwater mapping and from climate studies to deepwater surveys with the remotely operated submersible ROV Holland 1.

"The work conducted on the vessels continues to feed into the success in attracting EU funding to Ireland's marine science programmes that have been achieved by our strategic approach to marine science planning" explained Dr Peter Heffernan, CEO of the Marine Institute.

"The award of funding projects shows that partnerships between academics and small businesses can yield significant dividends in creating jobs, generating economic revenue and the supply of raw materials for new industries ranging from ocean energy and environmental monitoring technologies to marine-inspired pharmaceuticals and food ingredients" he further said.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
